11 Claims.

My invention relates to window supporting means and particularly to the supporting and guiding means for a window mounted in a door of a cabriolet type of body.

It has been the practice heretofore in providing windows for doors of the cabriolet type, that is to say, for doors ending at the belt line of the body, to provide a frame about the glass having extensions at the lower side edges which act as guides and supports when the window is in raised position. The guides operate in channels at the edges of the door and are provided with friction reducing means, such as balls and wheels, which not only permit the free operation of the frame but, being biased in opposite directions, prevent the lateral and longitudinal tilting movement of the window.

In practicing my invention I make possible such a support for a window in a door of the above mentioned type which is disposed in the vicinity of the wheel housing. In view of the presence of the wheel housing in the body, the rear lower portion ofthe door must be cut away, as is well known in the art, and for this reason the downwardly extending legs'on the rear portion of the window can no longer operate at the rear door edge. To overcome this difficulty I have offset the support at (the rear edge of the window inwardly thereofv sufliciently to clear the cutaway portion of the door. I have extended the glass guide channel of the door inwardly the same amount to provide surfaces upon which the rollers of the support may operate. As a further extension of the invention, I flange the ends of at least one, if not both, of the channels and provide a set of rollers which operate on the flanges and are diametrically disposed so as to eliminate the tilting in the plane of the glass which would otherwise occur or which would occur when such rollers are mounted in offset diametrical relation to each other.

Accordingly, the main objects of my invention are: to provide an offset support on the frame of a window glass which operates in an extended channel to permit the support to clear a cutaway portion in the door; to provide a channel with extended sides which encompasses one end por-'- tion of the glass to provide a surface upon which oflset' supporting elements of the glass frame 50 may be guided; to provide flanges on the edges of the channel on which guiding rollers may be retained in biased contact to prevent a tilting movement in the plane of said window glass; to construct an oifset support for a window glass such that the means provided to prevent the tilt- 1933, Serial No. 693,535 (or. asa -4s) ing of the glass in its plane will be oppositely disposed relative to each other; and, in general, to provide a support for a glass at the cutaway portion of a door which is simple in construction, economical of manufacture and positive in 5 operation.

Other objects and features of novelty of my invention will be either specifically pointed out or will become apparent when referring, for a better understanding of my invention, to the following 10 description taken in conjunction with the accompanying drawings, wherein:

Figure 1 is a broken view. partly in section and partly in elevation, of a door and window embodying features of my invention,

Fig. 2 is an enlarged sectional view of the structure illustrated in Fig. 1, taken on the line 2-2 thereof,

Fig. 3 is an enlarged sectional view of the structure illustrated in Fig. 1, taken on the line 3-3 thereof,

Fig. 4 is an enlarged sectional view of the structure illustrated in Fig. 1, taken on the line 4-4 thereof,

Fig. 5 is a broken sectional view of structure, similar to that illustrated in Fig. 1, embodying further novelty of my invention,

Fig. 6is an enlarged sectional view of the struc-- ture illustrated in Fig. 5, taken on the line H thereof, and 30 Fig. 7 is an enlarged sectional view of the structure illustrated in Fig. 6, taken on the line 1-1 thereof.

I have illustrated in Fig. 1, a door III for a cabriolet type of body which is to be employed adjacent to the wheel housing of the body in such manner as to require the lower right hand corner of the door to be cut away, as at H, to mate with the wheel housing portion of the body. A window I2 is disposed between the inner and outer panel of the door in the conventional manner, having a frame l3 thereabout for providing a finish to the glass and engagement for an actuating mechanism l4 by which the glass is moved to predetermined positions.

Arms IS on the regulator H are secured to a projecting plate l6 attached to the lower portion of the frame I3, having a slot ll therein in which the headed pins ill on the ends of the arms l5 slide. In this construction, I preferab1y provide a slot I! at the rear end of the plate IS in which the pin is of the rearmost arms l5 maybe disposed while the pin it. on the frontwardly disposedarm is preferably secured thereon during assembly to eliminate an additional slot in the plate l6 at which the pin IS on the rearmost arm l5 could pass during the operation of the window.

The main novelty of my invention resides in the method of supporting the window in the door against lateral and longitudinal tilting movements during the time it is moved or after it is disposed in predetermined position. In Figs. 1, 2 and 3, I have shown a method of supporting the front edge of the window frame by the channel element 2| provided as an extension of the front frame edge which is interconnected with the plate I 6 by the cross brace 22 to add strength to the assembly. A roller 23 and bell crank arms 25 disposed on either side thereof are mounted on a fixed pivot 24 within the channel element 2 I.

On one arm of the bell crank a roller 26 is pivoted to be biased outwardly, away from the channel element 2], by-a spring 21 mounted in engagement with the opposite arms of the bell crank. In this manner, lateral pressure is provided by the rollers 23 and 26 'to retain them in engagement with the sides of a glass run channel 28, provided on the left hand face of the door jamb. When two pairs of such rollers are employed, as illustrated more clearly in Figs. '1 and 2, any tilting movement laterally of the plane of the glass is prevented and the window may readily be operated.

A more serious problem obtains when constructing a similar guide and bracing means on the rear edge of the window above and adjacent to the cutaway portion l l of the door which mates with the wheel housing of the body. Referring more particularly to Figs. 1 and 4, I have illustrated a bracing construction which is new and novel. A channel element 29 is mounted on the rear door jamb having elongated sides 3| which project outwardly such an extent that the outer edges are disposed opposite to the cutaway portion II to be available to act as guides for an offset extension on the frame which will now be described.

Inwardly from the rear lower corner of the frame l3 a channel-shaped element 32 is provided, as illustrated more clearly in Fig. 4, mounted intermediate the side edges of the frame [3 inwardly from the rear frame edge. The element 32 is braced by a triangular shaped element 33 which may be a casting, an extruding metal portion or any suitable type of gusset plate, for strengthening the channel and retaining it in predetermined position. The channel 32 is provided with a double set of rollers 23 and 26 which are similar to those illustrated and described more particularly with reference to Fig. 2 and which function in the same manner relative to the sides 3|, as described above relative to the sides of the channel 28 disposed on the left hand side of the door. In this manner, both the front and rear edges of the door are supported against a movement laterally of the plane of the window in any of its positions. A strip of felt rubber or like material 30 may be provided on the web of the channels 28 and 29 to prevent the longitudinal tilting of the window.

A further extension of my invention, I have illustrated in Figs. 5, 6 and '7, the disposition of roller elements in aligned relation to each other which prevent a tilting movement of the window longitudinally of its plane of movement. channel on the left hand edge of the window, that is to say, the edge opposite to that having the cutaway portion II, is provided with a channel 35 which is similar to the channel 28 with the exception that the outer edges are flanged out-.'

wardly at 36to be employed as tracks with which a pair of rollers 38 contact.

The rollers 38 are mounted on a pair of arms .39, as illustrated more clearly in Fig. '7, which extend outwardly from a cup portion 4| in which a spring 42 is retained by a bolt 43 which extends through the web of the channel 2|. The tension of the spring 42 is adjusted by a nut 40 provided on the threaded end of the bolt 43. The cut 41 has an extending portion 44 provided with arms 45 which engage notches 46 in the edges of the sides of the channel element 2|. In this manner the rollers 38 are retained in cantilever suspension which maintains the rollers against movement relative to the tracks 36. The loading of the rollers may be regulated by the adjustment of the nut 40, which will remain constant in view of the fixed position of the arms 44 relative to the channel element 2|.

The channel 41 with the elongated sides provided at the rear portion of the door having the cutaway portion l I, is likewise provided with the outwardly extending flanges 36 upon which a pair of rollers 38 are mounted in the same manner as the rollers 38, above described, are mounted relative to the channel 35.

The pairs of rollers 38 are oppositely disposed so as to prevent the tilting of the window in its plane of movement. The pairs of rollers 23 and 26, above described, are mounted on either side o of the pairs of rollers 38 to prevent the lateral tilting movement of the window. In this construction, the window is retained rigid against movement either laterally or longitudinally of its plane of movement in spite of the fact that the lower right hand corner of the door is cut away to mate with the wheel housing, which prevents a supporting arm at its edge from extending downwardly within the door when the window is lowered.

While I have described and illustrated but a single embodiment of my invention, it will be apparent to those skilled in the art that various changes, omissions, additions and substitutions may be made therein without departing from the spirit and scope of my invention, as set forth in the accompanying claims.
